1978年起,我站的旱直播水稻单产连续稳定在千斤以上。近年来,我们认真总结推广了旱直播,使全场二万余亩水稻单产逐年稳步上升,千亩以上的千斤田不断出现,1983年全场平均单产达834.2斤,与七十年代相比增产近五成,改变了过去水稻产量低而不稳的局面。除抓了农田基本建设、秸秆还田、培肥地力等基本措施并根据栽培特点,选用了生育期较短、所需积温<3000℃的宁粳三号品种以外,在栽培上着重抓了以下几个关键措施。一、适时早播,掌握保苗技术,提高保苗率旱直播水稻在气温稳定通过10℃时播种初灌最好。按此标准,播种要在5月10日以
Since 1978, the dry-sowing rice yield of our station has been continuously stabilized above a thousand pounds. In recent years, we conscientiously summed up the promotion of direct seeding of dry seeding so that the output of more than 20,000 mu of rice fields in the entire field will steadily increase year by year. The average yield of the muse fields above 1,000 mu will continue to rise in 1983, reaching an average of 834.2 kg in 1983, up from the seventies Nearly 50%, changing the past, low and unstable rice production situation. In addition to grasping the basic farmland construction, straw, soil fertility and other basic measures and according to the characteristics of cultivation, selection of a shorter growth period, the required temperature <3000 ℃ Ningjing three varieties outside, focusing on the cultivation of the following A few key measures. First, timely early sowing, master seedling technology, improve the seedling coverage rate Direct-seeded rice in the temperature stable through 10 ℃ sowing the best early irrigation. According to this standard, sowing on May 10 to
